H Class Transfer Rooftop Chain H78A, H78B, H130, H131, H138
“H” Class Transfer Chain is often referred to as “rooftop” or “camelback” chain. It is designed to carry heavily concentrated loads, such as lumber, boxes, barrels and crates. It is usually intended for operation in troughs, in two or more parallel strands, with only the tops of the links protruding.
H Class Transfer Rooftop Chain H78A, H78B, H130, H131, H138
WLY Transfer Chain is available in two types: "H" Class Transfer Chain and Combination Transfer Chain. "H" Class Transfer Chain includes those numbered H78A, H78B, H130, H131, and H138. All "H" Class Transfer Chain is available only in riveted construction. "H" Class Transfer Chain numbered H 78A, H 130, and H 131 is made with peaked roofs. Chain numbers H138 and H78B have flat roofs.
Combination Transfer Chain includes those numbered C55A, C55B, and C55D. It is available only in riveted construction with peaked roofs.
Both types of these transfer chains, referred to at times as "rooftop" and "camelback" chains, are designed to carry heavily concentrated loads such as lumber, boxes, barrels, and crates. They are usually intended for operation in troughs in two or more parallel strands.with only the tops of the links protruding.
H Class Transfer Roof Top Chains Specifications
Rooftop transfer chains are special chains that are used to move bulk materials. They are also referred to as camelback chains or just transfer chains. This type of chain was introduced just after the invention of H-type mill chains to enhance bulk material handling and transferring in the aggregate and forestry industry. Presently, the rooftop transfer chain is found in almost any industry and applications requiring a high-strength conveyor transfer chain.

Uses of H Class Transfer Rooftop Chain
The primary purpose of a rooftop transfer chain is to function in troughs, usually on transfer conveyors with two or more parallel stands. These chains are designed with bevel tops on the links, which allow for transverse loading and unloading. They are commonly referred to as "camelback chains" and are favorable for their ability to carry heavy, concentrated loads, transport bulk materials, and products such as lumber, boxes, barrels, and crates within industries. It is important to note that these chains only operate in one direction and should not be installed in reverse. The speed of operation is dependent on the carried load and frequency, but the suggested speed is generally 100 feet per minute.

Sprocket for Rooftop Transfer Chain
We offer many types of rooftop chains in various sizes designed to handle different load capacities depending on the kind of forestry, packing, manufacturing, and building materials. What differentiates rooftop chains from other types of chains is that with a rooftop chain, the top piece or “roof” protects your products and equipment while reducing the sliding of material in conveyor lines.
Along with our chains, we also offer various sprockets for keeping your project moving and your operations productive.
